We are developing an intelligent tutoring system that helps beginning law students learn argumentation skills through the study of transcripts of oral argument sessions before the US Supreme Court. These transcripts exemplify complex reasoning processes in which proposed decision rules are evaluated by holding them against real and hypothetical cases. As a first step, we investigated (without c...

This paper describes an experiment where open and directed prompts were alternated when collecting speech data for the deployment of a call-routing application. The experiment tested whether open and directed prompts resulted in any differences with respect to the filled pauses exhibited by the callers, which is interesting in the light of the “many-options” hypothesis of filled pause productio...

Title: CAD in mammography: lesion-level vs. case-level analysis of the effects of prompts on human decisions Abstract OBJECT: To understand decision processes in CAD-supported breast screening by analysing how prompts affect readers' judgements of individual mammographic features (lesions). To this end we analysed hitherto unexamined details of reports completed by mammogram readers in an earli...

OBJECTIVES To determine the effectiveness of the cardiopulmonary resuscitation (CPR) audio prompts in an automatic external defibrillator in 24 lay subjects, before and after CPR training. METHODS Untrained subjects were asked to perform CPR on a manikin with and without the assistance of audio prompts. All subjects were then trained in CPR, and retested them eight weeks later. RESULTS Untr...

This paper reports on a qualitative study of students’ engagement with a Web-based inquiry environment aimed at prompting student reflection in processes of scientific inquiry. In order to demonstrate how prompts become structuring resources for students’ scientific inquiry, detailed analyses of students’ interaction processes are conducted. The students’ written responses to the reflection pro...

ActivePrompts are a new technology from Rhetorical, designed to offer a quicker and cheaper alternative to using voice talents and recording studios for the creation of an application-specific prompt library. Most speech user interfaces optimize the quality of their speech output by using pre-recorded prompts. In these applications, TTS is often considered to be a fall-back technology to genera...
